[PATCH,bpf-next 0/2] samples: bpf: update map definition to new syntax BTF-defined map

["Daniel T. Lee" <danieltimlee@gmail.com>]

Since, the new syntax of BTF-defined map has been introduced,
the syntax for using maps under samples directory are mixed up.
For example, some are already using the new syntax, and some are using
existing syntax by calling them as 'legacy'.

As stated at commit abd29c931459 ("libbpf: allow specifying map
definitions using BTF"), the BTF-defined map has more compatablility
with extending supported map definition features.

Also, unifying the map definition to BTF-defined map will help reduce
confusion between new syntax and existing syntax.

The commit doesn't replace all of the map to new BTF-defined map,
because some of the samples still use bpf_load instead of libbpf, which
can't properly create BTF-defined map.

This will only updates the samples which uses libbpf API for loading bpf
program. (ex. bpf_prog_load_xattr)

This patchset fixes some of the outdated error message regarded to loading
bpf program (load_bpf_file -> bpf_prog_load_xattr), and updates map
definition to new syntax of BTF-defined map.
